The PSU is overkill (anything over 600W is for a single GPU system), for the Graphics consider a 770 instead, and you're missing an aftermarket CPU cooler and storage (HDD/SSD). I assume you already have a monitor/keyboard/Windows.
But before that, what do you need the PC for? From your choice, it looks like gaming, but how much of a gamer are you? And your budget? Needs and budget are everything.
There is minimal improvement between Ivy Bridge and Haswell. Next to no performance boost, more restrictive overclocking, and desktop CPUs still aren't energy efficient (heat). On the other hand, the chipset supports more USB3/SATA III ports and a couple other new technologies that currently have 0 impact on the market. There is also the fact that 1155 is a dead-end socket, but I don't see anybody hurrying to abandon it yet.
Also, if you get Haswell, get 2400Mhz RAM. There's only a $20ish price difference, but gets a 7-15% boost in gaming and multitasking performance. Not much of a boost, but not much price increase.
